MARION — Sippican School had extra police presence Thursday, April 28 “out of an abundance of caution’’ after a staff member received a threatening phone call Wednesday afternoon, Superintendent Michael S. Nelson and Marion Police Chief Richard B. Nighelli reported.

At approximately 3:30 p.m., after school had already ended for the day, a staff member at the school received a telephone call in which an individual made non-specific threats against the school, according to the statement.

Marion Police responded to the school to provide an immediate police presence out of an abundance of caution, the statement said.

There were still some students in the school as part of the school's extended day program, the statement said, so families of those students were notified and the students were picked up by their parents while police were still on scene.
